Convert Kilobytes to Megabits (kB to Mbit)
1 kilobyte (kB) = 0.008 megabits (Mbit). 1 Mbit = 125 kB. Example: 15 kB = 15 × 0.008 = 0.12 Mbit.

How to Convert Kilobyte to Megabit
- 1 kB = 0.008 Mbit
- 1 Mbit = 125 kB
- Example: convert 15 kB to Mbit: 15 kB = 15 × 0.008 Mbit = 0.12 Mbit
Formula
Mbit = kB ÷ 125
Derivation from SI units:
- 1 kB = 1000 bytes = 8000 bits (decimal, SI).
- 1 Mbit = 10⁶ bits.
- 1 kB = 8000 bit ÷ 1000000 bit per Mbit = 0.008 Mbit
Both units are defined exactly, so the factor is exact. Kilobyte definition: kilobyte; Megabit definition: megabit.
Worked examples
- A reading of 16 kB converts to 0.128 Mbit.
16 kB × 0.008 = 0.128 Mbit - A value of 128 kB is 1.024 Mbit.
128 kB × 0.008 = 1.024 Mbit

Frequently asked questions
How many megabits are in 1 kilobyte?
1 kB = 0.008 Mbit.
How do I convert kilobytes to megabits?
Multiply the value in kB by 0.008, or divide it by 125. For example, 15 kB × 0.008 = 0.12 Mbit.
Is the kB to Mbit conversion exact?
Yes. Both units are defined exactly, and 1 kB is exactly 0.008 Mbit.
